Title: Voltage regulator of direct current dynamo for vehicle - incorporates PTC resistor in series with field to switch it off at high speed
Inventor: PENNITZ ALFRED
IPC: H02J7/22
Filed: 1979-03-23
Abstract: The dynamo for a road vehicle operates in parallel with a battery, the latter providing power at low dynamo speed. The normal electromechanical regulator is replaced by a resistor with a high positive temperature coefficient (9) in series with the field winding (3). The field and resistor are shunted across the armature (4). As the dynamo output voltage rises with increasing speed the field current increases and hence the heating of the resistor (9). By suitable choice of parameters the resistor achieves a high value at the permitted upper limit of generator voltage and thus effectively switches off the field. Cyclic operation then continues until the speed falls. A diode (11) isolates the dynamo from the battery at low speeds.
